About Zippy

Every student deserves a teacher’s full attention.

We started Zippy so good feedback no longer has to be rationed, so the thirty-first student gets the same close reading as the first.

The problem we set out to solve

Good feedback takes time teachers don’t have.

Naming the one thing that’s breaking a piece of writing, and showing a student how to fix it, takes about ten unhurried minutes to do well. Thirty of those is a working day no teacher has at 9pm on a Sunday. So it gets shorter, vaguer, later, until it’s a number and five words in red.

That’s the quiet trade every teacher makes: which students get your best, and which get “good effort, watch your tenses.”

It isn’t a failing of effort. It’s arithmetic. A class of thirty, marked properly, simply doesn’t fit inside a week, so the depth that helps students most is the first thing to go.

Why we built Zippy

So great feedback stops being a luxury.

Zippy reads every piece against your rubric and drafts the specific, kind, skill-by-skill feedback you’d write yourself if you had the hours, then hands it to you to approve. The thirty-first student gets the same close reading as the first. Every week.

It doesn’t replace the teacher; it gives every teacher the time to be one. By taking the marking pile off your desk, Zippy lets your judgement reach every student, not just the few you could get to.

Not faster marking, but personalised learning for every student. Not just the ones who can afford it.

What we believe

The principles we build by.

The teacher stays in charge

AI drafts; teachers decide. Nothing reaches a student without a teacher’s approval, and every approval is logged.

Built for our classrooms

Rubrics authored with ex-MOE educators, anchored to the standards local students are actually marked against.

Help students learn, not cheat

Zippy’s assistant gives hints and questions, never the answer. The learning stays the student’s own.
